I recently changed my Lynksis router (which was using WEP security) with an Apple Time Capsule which is using WPA/WPA2 personal security (because WEP is not available). On the network I have a new iMac, 3 Vista PCs and 2 XP PCs. The XP PCs and one Vista computer have no problem connecting to the network including internet access. The other two Vista computers however, while they can see the network they cannot connect to the internet. It seems that both of them have the same set-up of the other vista PC that instead can connect successfully (Vista Home Premium v 6 with SP2). I run a Windows update in order to see if there was any new security patch, but the problem persists. If I eliminate the WPA/WPA2 personal security from time capsule everything is working fine. Any hints ? Thx !
